IMPROVEMENT IN ENVELOPES.

Specification forming part of Letters Patent No. 117,795, dated YAugust 8, 1871; autedated July 28, 1871.

To all whom it may concern:

le it known that I, CHARLES E. MOMAHAN, of the city otl Elizabeth, in the county of Union and State of New Jersey, have invented an Improvement in Money-Envelopes, of which the following,` is a full, clear, and exact description, reference being had to the accompanying drawing l making a part ot' this specitcation, in Which- Figure 1 is a perspective view, and Fig. 2 shows more clearly the number of folds. The dotted lines in Fig. 2 show the envelope when fully folded.

The object of my invention is to inclose banknotes, checks, and other valuable papers in such a manner that they may be secure from any fraudulent attempt to extricate them Without leaving trace that they have been tampered with, as hereinafter more fully described.

I construct an envelope, of paper or other suitable material, which, in addition to the usual front and back pieces A and B and the lia-ps a b c, has the extra piece C, with the folding,I edges d d I thrilling' a safety-socket, in which the package is placed, bein creased in with and secured under the said folding edges, which, as they are folded, i'orm double corners, leaving' no opening,l \\'hatcver, so that, when inclosed within the main body of the envelope, no Wires can be slipped in to Withdraw the contents.

The pocket, as shown in Fig. 1, does not extend the who] e len gth or bread th ofthe envelope, Which must be mutilated when any effort is made to reach the secreted corners ,by a Wire, and, should the contents be reached, they could not be rem oved Without mutilation, being too tightly held down between the folds; also, in addition, the double-tolding flaps e e extending' from the front piece A, the outer ends of which are gummed to the back piece B, forming expansive sides, so that the envelope may be extended out far enough when necessary to receive the safety-pocket, which is folded in between the front and back pieces, the side lia-ps1) and e to be folded after the pocket is inserted in its proper place, and the top tlap atolap over all and to be gummed and sealed in the usual manner.

I claim- The extra pocket-piece C With thefolding edges el d d, when used in connection with an envelope construeted substantially as shown and described, and for the objects herein set forth.

Vitnesses: CHAS. E. MCMAHAN.
